Investigating the Properties of Oils

The cup viscometer measures the kinematic velocity of a fluid and the unit of viscosity measured by such a viscometer is centistokes (Viswanath). Purpose: To determine the viscosity of a given sample of lubricating oil of unknown viscosity, with the help of a Cup Viscometer and different commercially available oils of known viscosity. It can be hypothesized that as the viscosity increases, the flow decreases and thus the efflux time increases, i.e. substances with a higher viscosity would take more time to efflux from the cup viscometer to the beaker. Methodology: In this experiment a cup viscometer will be used to determine the viscosity of a sample of lubricating oil of unknown viscosity. The cup viscometer will first be constructed by using disposable Styrofoam cups and subsequently be used to measure the viscosity. The following equipment will be required to conduct the experiment: Three different types of commonly available oils with known viscosities, viz. Olive Oil Soyabean Oil Kerosene Oil A sample of the oil whose viscosity is to be determined, viz. ...Show more


Investigating the Properties of Oils Introduction: Viscosity is an inherent physical property of a fluid which confers resistance to flow (Viswanath). The viscosity of a fluid depends on several factors, including and not limited to, temperature and pressure…

The Effect Of Light Intensity On Photosynthesis Of Pondweed Plant
This proves that plant can only photosynthesize at the time of day. The rate of photosynthesis depends on the intensity of light. Other than this, there are other limiting factors of the process as well. Temperatures, Concentration of CO2, water, wavelength of light are some of the main limiting factors of the process.

Investigating the Impact of Poverty on Violent Crime
Citing instances of nations where crime rates are substantially lower in spite of high poverty, some authors argue that there is in reality no causality between crime and poverty. Others however strongly object citing instances such as majority of the population convicted serving out their jail terms come from poorer families or have relatively lower annual incomes.

The formation of carbonate rocks is affected by dissolution and is important in creating secondary porosity. Similarly compaction and cementation are critical to carbonate rock formation especially for the loss of porosity. Before cementation and compaction, other processes such as bioturbation and burrowing also affect carbonate rocks.
